DYEING-MACHINE.

Specification of Letters Patent.

Application filed September 3, 1910. Serial No. 580,418.

To all 'whom it may concern:

Be it known that I, vWILLLxu Sacmrrr DUnLL, a citizen of the United States, residing at r-Unsterdam, in the county of Mont-- gomery and State of New York, have 1n-' Stime'.

This invention relates to machines used in dyeing a11d,"analogous arts, and morev par-` and may be readily packed. Other objects will be in part obvious and in part pointed out hereinafter.

The lnventlon accordingly consists in the featuresof construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

ln the drawings wherein is shown one of the various possible embodiments of my invention, Figure 1 is a side elevation of the dyeing machine, part-1y in section for a clear disclosure; F ig. 2,is a sectional-plan view o-f the dye V'at, taken cn the line A--A, Fig. 1, the false bottoni shown broken away. Fig. 3 is a sectional plan view of the vat on a reduced scale on the line B, B. t

Referring now in detail to the drawings, wherein similar reference characters refer to similar parts throughout the several views The numeral 1 indicates a tank or vat, preferably cylindrical in shape and provided -in its bottom portion with orifices 2 and 3 and in its upperportion with orifices 4 and 5.

The numeral 6 indicates zin-elevated reservoir for the active fluid employed, in this instance dye liquor, and 7 indicates apump,

preferably of a rotary character, communiating with the bottom ofthe reservoir ntcutcd Oct. 8,191.2."

through the pipe S, and directly with they.,

upper and bottom portion, respectively, ofyl the tank by means of `the pipe 9 and its branches 10 and 11 leading from the orifices 5 and 3.

Branching from the pipe 8 is a pipe l2 leading to the central orifice 2 of the.

tank, and the latter pipe is also provided with a lead 13 provided with a stop cock 14, for a purpose which will hereinafter appear. At thc juncture of thc pipe S) and its branches 10 and 11 is a three way valve 15, and asimilar valve 16 is located at'- the point where the pipe 12 joins thc pipe 8. A pipe 17 leads directly from tho reservoir (i to the orifice at of the tank, and a faucet 1S is placed therein to control the flow therethrough. A suitable motor may bc provided to drive the pump 7. Y

Tith the parts arranged as thus far described, and assuming the reservoir G to contain a quantity of dye liquor suflicientl for the purposes of thc machine, the tank may be filled Awith the d vc liquor by opening the faucet 1S. An amount ofliquor is run into the tank sufficient; to lill it to a point above the orifice 5, said liquor also filling the pump 7 and the pipes S), 1t) and 12 and a portion of the pipe 8 leading from thc pump. The three way valves 15 and 16 are positioned so that when the pump is started the dye liquor is drawn from the upper portion of the tank to the pump through the pipes 10 and E) and forced through pipes 8 and 12 to the lower portion of the tank,` thence circulating through the tan'k, this circulaticn being continuous as long as the pump driven.- The liqiim in the tank may be removed and delivered into the reservoir by arrangingthe valve 15 to open the pipe 11 to the pump, and the valve 1G to cut out the pipe 12. By opening thecock 14 the tank may be emptied, and it will be obvious that by the described arrangement other desirable re-4 sults, which it is thought unnecessary to specify, may be obtained.

lVhen the material to be dyed is placed in the tank and thc dye liquor circulated as designed, said liquor tends to flow in more or less well defined currentsE or channels, a feature which is especially objectionable when the material to be dyed is iermeable, fibrous, etc., in which cases it'should be made to pass through the material. .To avoid this `for the distribution of theA dye liquor.

channeling 5, as it is called, the tank possesses characteristics which interfere with the production of individual currents, and provide for an even and equal current or flow of the liquor through all parts of the material, so that a uniform color is produced throughout the stock. To this end the tank embodies a receptacle for the material to be dyed, which in the present instance comprises a base or false bottom 19, spaced from the bottom of thetank and providing The material to be dyed' rests on the base and said base is preferably perforated or foraminous, whereby the .dye liquor is more uniformly distributed throughout the face of the material.

.In order thatthe dye liquor may reach all parts of the material', the receptacle is provided with passageways 20 discharging into the material by means of foraminous diaphragms, or partitions 21 spaced from the walls, of the tank and from each other, wherebyjthe receptacle comprises alternate foraminous and imperforate side walls, the diaphragms with the wall of the' tank den 'fning passageways 20 communicating with the space below the false bottom and opening against the material through the perorations. the base is recessed at diiferent point-s 22 and' the diaphragms 21 are alined respectively With the edges of` the recesses, and rise to such heightas may be necessary to span the material. Preferably the phragms are curved transversely and the perforations therein are'relatively angularly arranged to more eii`ectually distribute the dye liquor.A The upper ends of the passageways 20 are closed by means of plates 23 secured to the wall of the tank or'otherwise suitably fastened in place. These plates conform to the wall of the tank and to the curve of the diaphragms 21. The receptacle is further provided with a removable and adjustable cover, or superior material conning portion 24, of a shape corresponding with the plan of the tank as modifiedby the diaphragms 21, so that when placed in position it may be adjusted up .and down in the receptacle. Those portions of the edge of the cover opposite the diaphragms 21 are provided with upright lianges 25, conform` ing to the curved wall of the diaphragms 21, and the cover is designed to closely lit the imperforate portion of the tank Walls and the face of the diaphragms, so that in all positions of :uljustment any current of liquor between the meeting edges of the tank and cover practically prevented. Furthermen:`- when the cover is adjusted to a position below the upper end of the pas` sageways 20 the flanges 25 close the adjacent passages or openings in the diapln-agn'xs, thus serving as valves and direct` To establish these passageways,'

will now be described.

dia-

ing the flow of dye liquor to the space neath the cover.

The cover 24 .has an outlet or discharge opening intermediate the walls of the 'tank and preferably formed by a centrally artank, and provided at its upper end with a perforated vhandle 29. The top is lsecured in position on the tank walls by any suitable device, in the present instance by a series of clamps each consisting of a rod 30, pivoted to the tank and passing through a slot in the edge of the top, a nut 31 being provided to fasten the parts together. The cover 's slotted at 34 to accommodate the bailie plates.

Projecting into the receptacle are baiile plates 82, located on the side walls ofthe tanky between the partitions 21. rIhe purpose of these pla-tes will hereinafter appear. A steam or other pipe 33 to heat the dye liquor is provided beneaththe false bottom ofthe tank.

" The operation of the machine in dyeing The material to be dyed is packed in the receptacle as 4uniformly ras possible, the cover2t and top 28 are applied, and any pressure on the material is obtained by turning rod 27 by means of handle 29. The vat is filled with-dye liquor from the reservoir 6 by opening the cock 18. When the liquor has risen tothe proper height in the vat or tank, covering the material and the orifice 5, the valves 15 and 16 .a rod 27 threaded through'the top 28 of the f are adjusted to establish a continuous path from the orifice 5 through pipes 10 and 9, the pump 7, pipes 8 and 12 to the central orifice 2 in the bottom of the vat., Vlfhen the pump is driven in the proper direction, the dyeliquor will be drawn out of the upper portion of the vat through orifice 5 and forced into the .lower portion through orifice 2, entering the space below the false bottom 19 and spreading in all directions, passing through the perforations in the false bottom into the material. The liquorl also enters the passageways 20 via the recessed portion of the base, and enters the' material from the side through'thel foraminous partitions 21.

In this way the liquor is made to penetrate l the material both longitudinally and transversely, and as the liquor is constantly drawn vthrough the central opening in the cover, the Vtendency of the liquor is to converge toward the vcentral opening from all sides. Thus the body of liquor ,masses itself as it ows toward the outlet 2G, and there is no tendency to separatel into dei'ined currents or channels. The material is pressed against` the imperforate peri heral `portion of the cover and the liquor orcedto pass through the material to gain an outlet. Should the material be pressed away from the sides by the enteringdiquor, such asmight occur by improper packing, the baffle plates will prevent the liquor channelingaround the stock, and assist 1n directing it through the material. By the provision of the adjustable cover 24, the tank may be made to operate on less material than will fill the tank, as said cover may be lowered some distance below the upper edger of the diaphragms orparttions Qliby the adjusting rod 27, as previously explained. Notwithstanding this adjustment, the flow of liquor is still con` trolled as aforesaid by reason of the flanges 25, which cut oii' the flow through those per forations in the partitions which may be` above the cover.A

It will thus be perceived that the machine; accomplishes the Aobjects for which it was designed, besides possessing other advantages apparent from its construction. The unobstructed character of the receptacle url nishes a vat of large .capacity as well as one which may be readily packed. As many changes could be made in thel above construction and many apparently widely different embodiments of this inven' tion could be made Vwithout departing `from the scope thereof, it is intended that all matter contained'in the abovedescription or shown in the accompanying drawings shall. be interpreted as illustrative and not in a limiting sense. It is also to be .understoody that the language used in the following claims is intended to cover all of the generici and specific features of the invention herein'e described vand all statements of the scope of! the invention which, as a matter of langua e, might be said-to 'fall therebetween.
